Hi, TomAir9. Thanks for reaching out! Sorry to read about the difficulties you're encountering. We suggest removing the APK file you have downloaded and redownload it from our official download site: https://www.dji.com/downloads/djiapp/dji-fly

Please make sure to connect your Smart Controller to the internet when installing the APK file.
